William Blake's "Spring" uses lots of devices to create a simple, repetitive rhythm. For example, every line except for the final line of each stanza has three syllables, creating a regular syllabic meter. All of the lines, except for the final line of each stanza, also have end-rhymes forming rhyming couplets, such as "flute/mute" and "delight/night."

There is also in the poem lots of symbolism. For example, there are birds such as the "Nightingale" and the "Lark," which symbolize the freedom of youth. There is also reference to a "Little boy" and a "Little girl." Children in Blake's poems symbolize innocence, and appear frequently throughout the poems in his collection entitled Songs of Innocence.

There are also examples of alliteration in the poem, such as "Little lamb" and "Sweet and small." In the case of "Little lamb" the alliteration of the letter L helps to create a soft, lilting tone.

The opening line of the poem, "Sound the flute!" and also several lines in the final stanza, including "Let me pull" and "Let me kiss" are imperative sentences. An imperative sentence begins with a verb and sounds like an order. In this instance, the imperative sentences suggest the impatient excitement of the speaker.

Blake also uses lots of auditory imagery in the poem, to evoke the richness of beautiful sounds in the scene he describes. The poem begins with the sound of the flute and in the second stanza we have the crowing of the cockerel, which signifies the beginning of a new day. Also in the second stanza Blake evokes the merry sounds of children playing, again to suggest a scene full of joy and innocence.
